I ditched my iPhone 3G for a Desire and absolutely love it. I thought I'd struggle without iTunes, but honestly I'm much better off without it.
You say the music player on the Desire is not as good as the iPhone, but I actually find it much better.
I can see your point Samdy, not saying its a bad phone, in fact when i first saw it I was very impressed as it seemed much more modern and stylish than my existing 3gs. I loved it at first but very quickly i began to miss the iPhone, mainly for me was that i was struggling with the mp3 player although i accept that could just be me! A lot of smartphones out there now which i'm sure are all good, but for me iPhone ticks all the right boxes for me.
